Hi there! This is a little embarrasing, but I wet the bed up until I was in my early teens. My brother wet the bed too (but not as long). My nephew does it too, he just turned 7. Its definitly not abnormal for kids to wet the bed. It isn't deliberate or controllable. I actually turned out to have a problem with a valve down there, but not all children have a reason for it. It is pretty much something he will have to grow out of, hopefully it won't take as many years as it did for me. The best thing to do is not get mad at him and comfort him when this happens. Believe me, the child doesn't want to do it, its embarrasing and uncomfortable waking up in urine every night. A way to help it could be: no drinks before bed time, get up and wake your child up in the middle of the night to go potty, put pull ups on them before bedtime, etc. There are some examples. Its rough, I know, but hang in there...........you know it can't last forever!
